Embodiment Construction

[0064] Embodiments of the present invention will be described in detail below with reference to the drawings. Examples shown below show examples of liquid crystal display panels to make the technical idea of ​​the present invention more concrete. The present invention is not limited to the Examples described below.

[0065] In addition, the following embodiments show small liquid crystal display panels mainly used in display portions of mobile devices such as digital cameras and mobile phones. Also, a 2.2-inch panel with a resolution of 300ppi or higher and a pixel count of 640×480 pixels (VGA) or 320×240 pixels (QVGA) is displayed. Therefore, the pixel size is much smaller than that of a 40-inch or other liquid crystal display panel for televisions.

Abstract

The invention relates to a semi-transmission type liquid crystal display panel, every position divided by the signal lines and the scanning lines arranged in matrix way is provided with a first substrate (11) which forms and has a reflection part and a transmission part which is composed of pixel electrodes (15) with slots (17), a second substrate (19) which forms and has a color filter plate (21), a common electrode (22), and protuberances (23, 41), an orientation film (24) which causes a laminated and vertical orientation processing on the first and the second substrates (11, 19), and a liquid crystal layer (25) which is arranged between the first and the second substrates and has a dielectric constant with every anisotropy to be negative. When the electric field is not applied on the liquid crystal layer, the liquid crystal molecules are arranged vertically; when the electric field is applied on the liquid crystal layer, the liquid crystal molecules tilt according to the direction controlled by the slots and the protuberances and are arranged horizontally; in the semi-transmission type liquid crystal display panel, the slots are arranged at the central part of the pixel electrode of the transmission part, and the protuberances are arranged at the circumference of the pixel electrode of the transmission part and the central part of the reflection part.

Description

technical field [0001] The invention relates to a transflective liquid crystal display panel. In particular, it relates to a transflective liquid crystal display panel of the MVA (Multi-domain Vertically Aligned) method. Background technique [0002] Generally, liquid crystal display devices have the characteristics of thinness and low power consumption. In particular, TFT (Thin Film Transistor: Thin Film Transistor) liquid crystal display devices are widely used from portable terminals to large televisions. As a liquid crystal display panel used in a liquid crystal display device, there is a VA (vertically aligned) type liquid crystal display panel. The VA liquid crystal display panel is widely known as a liquid crystal display method that maintains a large viewing angle and responds quickly. [0003] Figure 4A It is a schematic cross-sectional view of a VA liquid crystal display panel. In the VA type liquid crystal display panel 60 , liquid crystal having a negative p...
